ATR/FT-IR studies of zeolite formation during alkali-activation of metakaolin

In this work the influence of the activator concentration on the inorganic polymer structure based on metakaolin was investigated. Changes in the aluminosilicate structure of the metakaolin during alkali-activation have been analyzed in detail on the basis of XRD, SEM and FT-IR analysis and ATR/FT-IR spectra as well. Based on the change of attenuated total reflectance FT-IR spectra over time at 80 degrees C, the zeolitization/geopolymerization process can be analyzed.
